`Specification of Letters `Patent No. 8,129, Vdated June 3, 1851.

To all whom t may concern? of" Leominster, ing the county of 'Vorcesterand State of Massachusetts, have invented a new and useful Improvement iin `Machinery for Cutting or Stamping Combs `Out ot' -Plates ofTortoise-Shell,`Horn, orother Suitable Material 5; and I do herebydeclare that the same is fully described andrepresented in the followingspecification,` the accompanying drawings, letters, gures, and ref#erences thereof. Y i

Figure 1 of thesaid drawings denotes `a top view of my improvedmachine.` Fig. 2 is `an end elevation of it, exhibitingthe end thereof,on which the driving crank .is` situated. Fig. 3, is a side elevation`ot' it. Fig. Ll, isa vertical and transverse section and Fig. 5, is avertical central andlongitudinal section of it.` Fig. 6, is an undersideview of the series of cutters. g y g In the said drawings A representsthe frame work for supporting the Operative parts of the mechanism to behereinafter described. I

B is the driving shaft supported and made to revolve insuitable boxes atC, C, and having` a crank D or other suitable mechanism properly appliedtoit for the purpose of putting it in motion or revolution. The drivingshaft carries and"` supports a fly wheel F, to whose perimeter a seriesof rollers Gr, G, Gr, &c., are connected as seen in the drawings. Eachof the said rollers being placed inthe vertical plane of some one of aseries of levers H H H, which turn on aicominon pin or i'ulci'um I, atone end while at theother end each oit' the said levers rests upon oneof the series ot cutters or stamps-L, L, L, &c.` The said series ofcutters Or stamps is disposed in the middle of themachine, and issupported by and made to move vertically up'and down within a suit-ableframe M, and although each cutter is depressed or forced `downwardswhenever the lever directly over it is depressed, yetsuch cutter isafterwards raised bythe retractive power of two springs N, N, applied toit, and extending toward it from the main frame work as seen in thedrawings.

Fig. 7 denotes an edge view of one of the cutters in which it will beseen `that lsuch .cutter is formed with one long cuttiiig edge S. COOK,

By inspectionof Fig. G, it will be seen that the several smaller cuttingedges b, 22,12, and c, c', c, of the cutters are not disposed instraight lines with each` other, but are arranged in curved lines andthis for the purpose ot producing from a sheet of tor-` toise shell orhorn, what is usually understood by combniakers as the bottoming,

which bottoining co-nsists in arranging the .roots of the tooth, aswellas their points in curved lines as` represented in e, s, in Fig. 8,which denotes a top` view of a plate or horn or shell, and exhibits thelines `of thecuts madethrough it in order to produce twocombs. i

suitable carriage orbed for `sustaining and holdingtlie plate of horn orshell to be operated upon, is placed under the cutters as seen at, O,and is caused tofslide'in or out or upon` parallel ways or -rails P, P,

`raised upon the bed plate Q, ot the frame A. Aclamping frame `R formedof two bars 7L, z, united by rods c', z', is hinged at oneend to one endof the carriage for supporting the` comb plate, such frame having `abent lever Z, applied to its other end in such manner as to enable aperson by means of it, to not only confine the clamping frame down, uponthe plate of shell, and thereby confine the latter to the carriage, butto move the carriage inand out or upon its supporting rails.

By the action of the rollers of the fly wheel, which rollers operateupon the levers under them` in `regular succession, the several cuttersare successively depressed or forced "downward into and through theplate of horn or shell, which may be arranged directly under them, andsupported `by and upon the carriage hereinbeiore mentioned. In combmachines it has heretofore been customary to cut the teeth of two combsby thefsuccessive blows l kota single cutter which in the interval,` of`each two blows, has moved a suitable distance, and

in a suitable manner', to produce the `taperation of the single cutteris better than that of a series of cutters all fixed in a block andsimultaneously driven through the horn or shell because the horn orshell is very much strained compressed and liable to be broken by theaction of such a series of cutters which may be said to be stationarywith respect to one another. The bottoming of the combs can be producedby such a series of cutters, but it is attended with a seriousditiiculty above mentioned. To overcome such ditiiculty and to obtainthe advantage ot' the single cutter, without any material additionalexpense, l have produced the improved machine as herein described, bywhich l not only gain such advantages but also the additional one offorming the two combs with the curved bottoming, as I have aboveexplained.

I do not claim the invention of a single chisel made to operate bysuccessive blows or cuts, each of which is in advance of an other and soas to create a series of cuts through a plate of horn or shell, such aswill separate such yplate into two combs without what is termed abottoming that is to say, with the roots of the teeth of each of thesaid combs in a straight line and not in a curved line, as they are whenmade with the bottoming nor do I claim a die so made of stationarychisels or cutters (that is to say those which are immovable withrespect to one another) and for the purpose of enabling a person bypressure of the whole series of cutters at once, against a plate of hornor shell to separate it into two of different and the required lengths,so asl to produce the separation of two combs from s a comb plate,substantially in the manner and with the bottoming to their teeth ashereinbefore specified.

ln testimony whereof have hereto set Y my signature this thii'ty-iirstday of December A.. D. 1850.
